Bitwig thinks window is open after self have called clap_plugin_gui->destroy() to acknowledge

[logos-maker]

Bitwig doesn't release the button SHOW PLUG-IN WINDOW after I have called...
void (*closed)(const clap_host_t *host, bool was_destroyed);
...when the user clicks down my floating window.

...and Bitwig responds with calling...
clap_plugin_gui->destroy()
... as expected and the plug closes the window.

But that button in the Bitwig interface works when I press the SHOW PLUG-IN WINDOW, and bitwig calls create show and destroy with it as expected, so that works as expected.

What can that be the cause of?

But I wonder what is the flag was_destroyed for? in...
void (*closed)(const clap_host_t *host, bool was_destroyed);

If I set it to false Bitwig calls clap_plugin_gui->destroy()
but if I set it to true Bitwig newer calls clap_plugin_gui->destroy()
